We report the case of a 70-year-old man presenting with a high fever, sore throat, and wet cough who was admitted to our hospital with a clinical diagnosis of community-acquired pneumonia. Chest radiograph and chest computed tomography on admission showed infiltrative shadow in the right middle lobe. Blood culture results were positive for Neisseria meningitidis as determined by culture growth on chocolate agar and confirmed by mass spectrometry. A 14-day course of sulbactam/ampicillin resulted in resolution of his clinical symptoms and imaging findings. N. meningitidis is a gram-negative diplococcus that is a resident bacterial species detected in sputum culture. However, as observed in this case, N. meningitidis can occasionally be identified as the etiologic agent of community-acquired pneumonia. As such, this pathogen should be considered as part of the differential diagnosis of this condition.
